This year, the EuroBlech 2000 in Hannover was
a milestone for the hydroforming industry.
Last Update February 21, 2001
Let's talk hydroforming and Hydroforming
at its best were the slogan of the two
major hydroforming machines builders.

as a part of the Th. Graebener Group ( further
information under http://www.graebener-group.de )
took part in the EUROBLECH Exhibition for the
first time. As a conclusion we can say that we
had a tremendeous number of requests for
information on our offered hydroforming
technology and it is certain that we will
participate at the next EUROBLECH.
GRAEBENER HYDROFORMING exhibited parts which are
actually produced in in different customer's sops.
With these parts we achieve cycle time reductions
by more than 40 % with our new or retrofit of
existing presses compared to competitor's presses.These
reductions are a result of GRAEBENER's open
control concept PressPro\'99, decentralized Axis
controllers as well as the possibility to
optimize the programme in the process parameters.
We had requests for quotations out of all
industrial applications for Tubular Hydroforming
as well as Sheet Metal Hydroforming. With Sheet
Metal Hydroforming a trend is shown that more and
more companies want to start with this technology
to use the advantages of Sheet Metal Hydroforming
for niche markets as well as small batch
production.Due to the fact that most of the
Hydroforming Presses offered in the market are
either used for Tubular Hydroforming or Sheet
Metal Hydroforming and therefore often have a low
usage factor GRAEBENER HYDROFORMING designed
their presses for application of both
technologies to guarantee an economical
exploitation of the Hydroforming Presses. (Dietmar

Hydroforming at its best at the Euroblech 2000 -
positive result for Siempelkamp Pressen Systeme
"Hydroforming at its best" was
presented by Siempelkamp Pressen Systeme - SPS,
Krefeld at the Euroblech 2000 show in Hanover
last December. Once again Hydroforming was the
topic of the show. Numerous exhibits on SPS'
stand documented the developments that were
intensively brought forward by SPS in cooperation
with its partners in the automotive industry
during the past years.
Two specific exhibits were of particular
interest to the visitors. The spaceframe concept
of a SUV was the eye-catcher at SPS' stand. A 1:18
model of a Jaguar E-type sports car which was
hydroformed from a welded aluminum tube by an
innovative manufacturing process proved the
enormous potential of this process that allows
expansions of more than 100 %. In cooperation
with an industrial partner SPS are continuously
developing and improving this process to push it
forward for applications in prototype and series
production of "real" parts.
Apart from innovative concepts and hydroformed
components SPS also presented new developments
for production methods. A fully-operative model
of a Sheet Metal Hydroforming device demonstrated
in practice the variety of applications this
innovative technology offers. With this new
concept that was specifically developed from
conventional tube hydroforming together with the
"Lehrstuhl für Umformtechnik" (Institute
for Forming Technology) of the University of
Dortmund sheet metal is forced into a die cavity
by water at high-pressure (up to 2,000 bar). The
sheets will take the shape of the die contour and
retain this shape durably with repeatable
This innovative technology promises a
considerable potential of development and
advancement. Even large-sized workpieces or
material with particular forming properties that
are normally difficult to form can be
manufactured economically. The first machine of
this type will be delivered by SPS in 2001.
An improved hydroforming concept, presented at
the Euroblech 2000 show for the first time raised
the visitor's attention. This concept combines
the advantages of an economic short-stroke
principle with the advantages of an optimum
accessibility for tool change and part handling.
As in past years SPS participated together
with other members of the Siempelkamp group of
companies which demonstrated once again combined
competence to jointly accomplish complex
manufacturing tasks. With numerous interesting
and promising contacts that were established in
Hanover the Euroblech 2000 show has once again
turned out a great success for Siempelkamp
Pressen Systeme. We are looking forward to the
next Euroblech in 2002 but first the SAE 2001 in
Detroit (March 5th - 8th, Cobo Center, booth 5032)
is waiting for us!
